The Safariland Solis Holster combines the security of ALS with the release speed and draw simplicity of an open-top design. Solis is compatible with most compact red dot sights. Available in both light-bearing and non-light-bearing configurations. The ALS secures your weapon automatically as it is holstered, yet still allows a fast, natural draw with the swipe of the thumb release as you acquire your shooting grip.Features :Fits GLOCK 17/47/49 with Small LightSTX Black FinishALS Retention
